Its fan will go ON when reaches 70 C, and above 80 C is critical and suddenly it will shutdown, it seems the fan can't catch up with the heat. This happens when using internet for long and big download or playing online (whatever force the cpu to run hard)

Then I found the above thread, and I made up a simple GUI for it, and would like to share it with you.

Install:
Just click the pet package. Don't forget to refresh menus (4.2x) or fixmenus from terminal and restart window manager (4.1x). It comes with a menu entry

How to use:
The GUI will pop up along with a message that tells the status os your ibm acpi fan. Read it, find the line which tells available fan speed level options. In my case only 0 - 7 (0 = off), some models may have disengaged and auto level

Select the speed level from drop down menu and press apply

Once you applied, then everytime your computer start up, it will activate ibm_acpi and activate the fan accordingly (see /root/Startup/ibm_acpi_fan)

Note: The usual acpi makes the fan to go on at 70 C point, so to test I apply this fan to go on at 45 C, then force the cpu to work hard until 70C, then let cpu cool down. Suprisingly, the regular acpi still controls the fan, it goes off when temp reached below 70 C. So, be aware._________________My apps

I had a report of a problem with the fan in my puplet section
stangly only when a full install was selected which I can't confirm since mine is working correctly and I still haven't been given any detailed information yet so it is listed still as "unconfirmed "
and maybe your GUI is a good solution to this I just need to sort out
for what other versions your GUI could work for also
or be modified to add in more models

I attached an info get script here for those having problems with the fan it will provide me with more information about the problem to be correctly identified

I've just thrown Puppy a USB stick on a ThinkPad X60, but found its running quite hot. I've tired Trio's control util and installed the pup, but when I select a fan level it's not actually affecting the fans (though it shows no errors).

I've used big_bass's script and the results are here. I'm a total newbie to Linux though (just Atari TOS and Windows for me before today) so could really use some help with this.

Hi there, my turn to resurrect an old thread. In answer to your two posts - yes, I have an X60s (lovely machine, almost identical to the X60) and have the heat problem. There are several steps to handling this in my experience.

1. Reduce heat generation... In BIOS, disable every device you don't use. If you have Intel 3945 wireless card (I did), replace it with an alternative (Google for examples - I chose the Atheros one, under £5 on eBay now). If you can afford to, replace the HDD with an SSD (that's on my list for the future).
2. I am sure you have found the program in Puppy, Menu/System/Hardware Information which allows you to read the ThinkPad's sensors and see current fan speed and temperature. The fan is quiet and you may not notice fan speed changes immediately. Also, these systems are designed to run quite hot. Any temperature in 50-60C range is quite OK, though if you have the Intel 3945 wireless card, the palmrest will be too hot by then.
3. You need to modify the acpi_thinkpad module to allow user control of fan speed. Two commands (i) modprobe -r thinkpad-acpi (ii) modprobe thinkpad-acpi fan_control=1
4. Then the IBM FAN 'pet' in the post above works. It does not give automatic fan control but enables you to push up the fan speed when you see a problem of when the sensors indicate one. At fan speed setting of 7 my fan is reported as running at 4250RPM which is about as expected. The auto setting seems to let the fan go too slowly.
5. I have succeeded in getting auto fan control working on Ubuntu/Mint (Google for ThinkPad-Fan-Control, very useful program, or see here http://www.thinkwiki.org/wiki/How_to_control_fan_speed#Automated_program_-_Simple_ThinkPad_Fan_Control ) but not yet got this working on Puppy.
